Chalk a big one up for metals in the ongoing battle with engineering plastics for applications that reduce weight of cars. Novelis Inc, an Indian-owned spin-off from Alcan, will supply aluminum sheet for the hood of the 2008 Buick Enclave. Novelis describes itself as the world’s leading supplier of high performance aluminum sheet for use in automotive applications. The Enclave is a beautifully designed vehicle that was first shown at the Detroit Auto Show in 2006. It’s a cousin to GMC’s Acadia crossover vehicle, which also features an aluminum hood made with Novelis sheet. Both vehicles are built on GM’s all-new Lambda unibody architecture. Aluminum sheet for the Enclave and the Acadia is supplied from Novelis plants in Oswego, NY, and Kingston, Ontario
NASA's MAVEN spacecraft has entered Mars' atmosphere, carrying instruments to help Earthlings figure out what happened to it. Launched last November, the spacecraft arrived at the red planet right on time after a journey of 442 million miles.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
